Cerebral atrophy is a common feature of many of the diseases that affect the brain. [1] Atrophy of any tissue means a decrement in the size of the cell, which can be due to progressive loss of cytoplasmic proteins. In brain tissue, atrophy describes a loss of neurons and the connections between them.
A diagnosis for cerebellar degeneration is regarded after any of the aforementioned signs and symptoms surface. For genetically classified forms of cerebellar degeneration, genetic testing can be carried out in order to confirm or deny the diagnosis, where this form of testing is only possible if the gene responsible for the cause of the ...
Certain signs and symptoms of MSA also occur with other disorders, such as Parkinson's disease, making the diagnosis more difficult. [ 40 ] [ 41 ] [ 42 ] Features characteristic of OPCA include progressive cerebellar ataxia , leading to clumsiness in body movements, veering from midline when walking, wide-based stance, and falls without signs ...
The symptoms include poor balance and difficulty walking. Chronic cough and difficulty swallowing may also be present. Clinical findings include ataxia, sensory neuropathy, and absence of the vestibulo-ocular reflex. The syndrome was initially described in 2004. [1] In 2019, the cause was identified as biallelic pentanucleotide expansion in the ...
The most frequent initial symptoms of Bickerstaff brainstem encephalitis are drowsiness, gait disturbances, and diplopia. Throughout the course of the disorder, almost every patient develops ataxia and external ophthalmoplegia .
Corticobasal degeneration (CBD) is a rare neurodegenerative disease involving the cerebral cortex and the basal ganglia. [1] CBD symptoms typically begin in people from 50 to 70 years of age, and typical survival before death is eight years.
The impact on life expectancy depends on the individual condition, [9] but is usually severe without treatment. [1] [3] It's estimated only 25–29% of people affected survive to adulthood, and only 10% to the age of 50. [1] The median life expectancy is around 9 years, and the average life expectancy is 16.3 years. [1]
The prognosis for any individual with PFBC is variable and hard to predict. There is no reliable correlation between age, extent of calcium deposits in the brain, and neurological deficit. Since the appearance of calcification is age-dependent, a CT scan could be negative in a gene carrier who is younger than the age of 55. [30]
